Cleaning Up Perl

Part of mastering Perl is controlling the source code, no matter who gives it to you. People can usually read the code that they wrote, and usually complain about the code that other people wrote. In this chapter I’ll take that code and make it readable. This includes the output of so-called Perl obfuscators, which do much of their work by simply removing whitespace. You’re the programmer and it’s the source, so you need to show it who’s boss.
